Chapter 10, Problem 77AP
Review. As shown in Figure P10.77, two blocks are connected by a string of negligible mass passing over a pulley of radius r = 0.250 m and moment of inertia I. The block on the frictionless incline is moving with a constant acceleration of magnitude a = 2.00 m/s2. From this information, we wish to find the moment of inertia of the pulley. (a) What analysis model is appropriate for the blocks? (b) What analysis model is appropriate for the pulley? (c) From the analysis model in part (a), find the tension T1. (d) Similarly, find the tension T2. (e) From the analysis model in part (b), find a symbolic expression for the moment of inertia of the pulley in terms of the tensions T1 and T2, the pulley radius r, and the acceleration a. (f) Find the numerical value of the moment of inertia of the pulley.

This problem describes one experimental method for determining the moment of inertia of an irregularly shaped object such as the payload for a satellite. Figure P10.47 shows a counterweight of mass m suspended by a cord wound around a spool of radius r, forming part of a turntable supporting the object. The turntable can rotate without friction. When the counterweight is released from rest, it descends through a distance h, acquiring a speed v.

A 392 N wheel comes off a moving truck and rolls without
slipping along a highway. At the bottom of a hill it is rotating at
27.5 rad/s. The radius of the wheel is 0.600 m, and its moment
of inertia about its rotation axis is 0.800MR2. Friction does work
on the wheel as it rolls up the hill to a stop, a height h above the
bottom of the hill; this work has absolute value 2600 J.
